is effective in all operating modes. If the parameter contains the value 0x00h, no timeout is
activated.

be inserted by the host via serial interface (see Figure 1)

An address comparison (M- and A-field) takes place upon reception of a wM-Bus
telegram via radio. If the comparison is successful then the output of the telegram takes
place according to Figure 5. (M- and A-fields are filtered)
If this value is set to 0x01, then block 1 of the module

is inserted again (the content for C-, M-, and A-fields have to be transmitted vie the serial
interface by the host, see Figure 2)

is checked during reception (and therefore is transmitted unmodified via the serial
interface, see Figure 4)
